Abstract

La présente invention a pour objet un procédé de traitement et de manutention de laitier metallurgique, notamment de laitier de haut fourneau soumis à la granulation humide par un quelconque procédé connu. Elle est caractérisée en ce que le mélange laitier granulés-eau est amené à l'intérieur d'un dispositif rotatif, que l'eau y est séparée par filtration, alors que le laitier granulé est déplacé suivant un chemin circulaire sensiblement jusqu'au sommet du dispositif rotatif, qu'à la fin de sa trajectoire semi-circulaire il tombe librement vers le bas et est recueilli par un moyen d'extraction qui l'évacue hors du dispositif rotatif et l'amène vers un quelconque moyen de stockage ou de transport. Elle se rapporte à un procédé et installation de traitement et de manutention de laitier métallurgique.The present invention relates to a process for treating and handling metallurgical slag, in particular blast furnace slag subjected to wet granulation by any known process. It is characterized in that the granule-water dairy mixture is brought inside a rotary device, that the water is separated there by filtration, while the granulated slag is moved along a circular path substantially to the top. of the rotary device, that at the end of its semicircular path it falls freely downwards and is collected by an extraction means which evacuates it from the rotary device and brings it to any means of storage or transport. It relates to a process and installation for treating and handling metallurgical slag.
